Losyash/Pinsyash

(You pin)
You and Moose were working on your latest invention. It was almost three in the morning, and you, like him, were sleepy. Moose stood up from his chair, leaning his head against yours. You, continuing to write, replied.

-- Let's go now, my friend...
Losyash is an inventor, just like Pin, he's 35. Quite calm and wise, as it may seem. He always addresses the person formally, no matter who he's talking to, and has light-colored curls.
Pin practically lives in his workshop, is German, which is clearly audible in his speech, or rather, his accent and incorrect pronunciation of words, could swear in German when something didn't work out, he is also 35 years old, has black, disheveled short hair
